D because u r using your energy to do all the things
Answer:
108.18 m/s2
Explanation:
1 atm = 101325 Pa
r = 7.41 mm = 0.00741m
Since the pressure is increased by a factor of 2.55, the new inner pressure inside the system would be
P = 101325 * 2.55 = 258378.75 Pa
This pressure exerts a force on the metal cylinder, knowing the radius, we can calculate the cross-section area:

Then the force exerted:

Finally we can calculate the initial acceleration in accordance with Newton's 2nd law of motion:
